While visual representation is often listed as the second dimension of interaction design (the others being words, space, time, and behavior), in many ways it is the first.

As visual mediums, sites and apps communicate primarily in visuals, and even written language must be presented carefully through typography choices, sizing, alignment etc. Perhaps even more important, as sight-based creatures, humans are accustomed to making split-second decisions on appearance alone. These instantaneous responses are deeply linked with emotions, and so your interface’s look immediately affects how your user feels about the site.
